The Players – Sen. Olympia Snowe, R-Maine

Career Path: Snowe served 16 years in the U.S. House before being elected to the Senate in 1994.

Role in Health Care Reform, 1993-1994: None.

Why She’s a Player Now: Sen. Snowe is the only Republican lawmaker thus far to vote yes for a health-overhaul bill. Democrats courting her for months because of her moderate leanings, but an affirmative vote on final legislation is still up in the air. Snowe supports a “public option trigger,” which is not currently in Senate legislation.
